Cosmopolitan v3.9.2
Cosmopolitan's Windows support may finally be feature complete. It's now
possible to send signals between processes using kill() on Windows. Ten
new torture test programs have been written to tease out more fixes and
offer a high level of assurance that signal handling is correct. Some of
these tests are good enough to deadlock the signal handling of UNIX OSes
but not our signaling module for Windows. They also demonstrate that our
Windows signal handling actually outperforms many UNIX OSes at latency.

- d730fc6 Make NESEMU1 demo more reliable
This release includes a new build of cosmos, which is our collection of
prebuilt open source software. Special care has been placed into making
sure programs like Emacs, vim, wget, curl, etc. all work well on Windows.
Instructions are provided for its installation on UNIX and Windows systems.

Cosmopolitan v3.9.0
Cosmopolitan Libc makes C a build-once run-anywhere language, like Java, except it doesn't need an interpreter or virtual machine. Instead, it reconfigures stock GCC and Clang to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best possible performance and the tiniest footprint imaginable. For further details, read Cosmopolitan Third Edition, the Cosmo README, and the Cosmopolitan Toolchain README. Prebuilt software is available on https://cosmo.zip/

Improvements
Your malloc() function is now more scalable on Linux Aarch64 and other
platforms, where it previously was not working as well as advertised.
- 0a79c69 Make malloc scalable on all platforms
Cosmopolitan Bash now works better on Windows. For example, if you start
a process that redirects stderr to a file, then your entire process tree
will now be able to cooperatively write to that file. When you update it
is recommended that you upgrade all your cosmos binaries at once.
Improvements have been made to cosmocc and libcxx which made it possible
for us to compile Clang as an APE binary.
- 77d3a07 Fix std::filesystem
- 0d7c272 Don't use sendfile() in libcxx
- 18964e5 Fix remove() directory on Windows

- 01b09bc Support printf %n directive
- 3dab207 Remove mkfifo() prototype
- d0360bf Introduce cosmoranlib
Some upstream dependencies have been updated. In particular, Musl locale
handling is more true to the way it works upstream. You may need to have
setlocale(LC_ALL, "C.UTF-8") in your main() function for certain POSIX
functions to work the same way they did previously by default.
- bb815ea Update Musl Libc code
- ff1a0d1 Upgrade to superconfigure z0.0.51
